Daimon (The Prequel to Half-Blood)

For three years, Alexandria has lived among mortals - pretending to be like them and trying to forget the duty she'd been trained to fulfil as a child of a mortal and a demigod. At seventeen, she's pretty much accepted that she's a freak by mortal standards. . . and that she'll never be prepared for that duty.

According to her mother, that's a good thing.

But as every descendent of the gods knows, Fate has a way of rearing her ugly head. A horrifying attack forces Alex to flee Miami and try to find her way back to the very place her mother had warned her she should never return - the Covenant. Every step that brings her closer to safety is one more step toward death. . . because she's being hunted by the very creatures she'd once trained to kill.

The daimons have found her.
